Monitoring of the Training Load and Well-Being of Elite Rhythmic Gymnastics Athletes in 25 Weeks: A Comparison between Starters and Reserves.

The objective of this study was to monitor the training loads (TL) and well-being of elite rhythmic gymnastics (RG) athletes, as well as compare these variables between starters and reserve gymnasts during 25 weeks of training. Ten athletes from the Brazilian national RG team (17.4 ± 1.1 y of age) were monitored during the general preparatory period (GPP), specific preparatory period (SPP), and pre-competitive period (PCP). The internal TL was quantified with the use of sessional ratings of perceived exertion (sRPE). We assessed well-being daily with a well-being scale. The TL, duration, monotony, and strain were calculated weekly. We found that the internal TL and session durations were 9242 ± 2511 AU and 2014 ± 450 min, respectively. The internal TL, strain, and monotony were greater in the PCP than in the GPP and SPP for starters. In the SPP, there were statistical differences in internal TL (p = 0.036) and strain (p = 0.027) between starters and reserves. In the PCP, there were also statistical differences between starters vs. reserves athletes regarding internal TL (p = 0.027) and strain (p = 0.05). There was no statistically significant difference in well-being between the periods assessed. In conclusion, RG athletes display a higher TL magnitude during the PCP, whereas only reporting non-significant minor variations in well-being. In addition, there is a discrepancy in the TL between starters and reserves.

Effects of different multicomponent training methods on functional parameters in physically-active older women.

BACKGROUND: Negative functionality changes are among the effects of aging. The multicomponent training performed on conventional machines or with new implements and features directed to daily activities is strongly recommended among attenuation strategies. However, the efficiency of both types of training is not yet clear in the recent literature. The aim was to compare the effects of different multicomponent training methods on functional parameters in older women. METHODS: Thirty-seven volunteers were randomly selected into the functional multicomponent training (MFT: N.=15), traditional multicomponent training (MTT: N.=14) and control group (CG: N.=8). They were assessed in the tests: Six-Minute Walk Test (6MWT), Ten-Minute Fast Walking Test (10FWT), Timed Up and Go test (TUG), Functional Reach Test (FRT), Ankle Test (AKT), Sit To Stand Modified test (STSM), and quality of life (QOL). ANOVA (3×2) followed by the Bonferroni post-hoc was used, adopting P≤0.05 for statistical significance. RESULTS: When compared pre-post values, MFT showed significant differences in all functional tests evaluated (AKT: P<0.01; STSM: P<0.01; FRT: P<0.01; QOF: P<0.01; 10FWT: P<0.01; 6MWT: P<0.01; TUG: P<0.05). In the same comparison, MTT showed a significant change in all tests (AKT: P<0.01; STSM: P<0.01; FRT: P<0.01; QOF: P<0.05; 6MWT: P≤0.05; TUG: P<0.05) except 10FWT. When compared to CG, MFT showed a significant difference in all walking tests and MTT showed a better performance in 10FWT and TUG. CONCLUSIONS: Both experimental protocols were effective to improve functional parameters in older women. However, the MFT was performed better in most tests that required efficiency in gait ability.

Reliability of a Test for Assessment of Isometric Trunk Muscle Strength in Elderly Women.

OBJECTIVE: The aim of this study was to analyze the reproducibility of a protocol using the maximal isometric strength test of the trunk in elderly women aged above 60 years, without low back pain. METHODS: Twenty-one physically inactive elderly women, who had not engaged in any activity or exercise program in the past three months, participated in the cross-sectional study that consisted of two days of evaluations for the maximal isometric strength of the extensor and flexor muscles of the trunk, with a 48 h interval between the sessions. A platform with fixed seating was used, which allowed the fixation of the hip and lower limbs, with a load cell connected to a linear encoder. To verify the reliability of the test, the interclass correlation coefficient, variation coefficient, minimum detectable difference (MDD), standard error of measurement, and Bland-Altman graphs were calculated. RESULTS: No statistical difference was observed between the first and second evaluation, which indicates that there was no learning effect. Interclass correlation coefficient values were classified as very high and high for extensor (0.98) and flexor (0.86) muscles, respectively, besides low variation (9% for both muscle groups) and acceptable values for minimum detectable difference (extensors = 51.1 N, flexors = 48.9 N). In addition, the Bland-Altman analysis revealed low bias and values within the limits of agreement. CONCLUSION: It is concluded that the test of maximum isometric strength of the trunk in healthy and trained elderly people presents high reliability. These values proved to be reliable if performed in at least two evaluation sessions, which confirms the hypothesis of the authors by the consistency of the measurement test.
